Can some one show me two example with using PIL module in ZOPE
1. creating an image from inputed data an safe into zope
for example: given x,y,r as a center coordinate and radius and draw a circle and save it as circle.jpg
2. read an exisiting image, edit it, and save it
for example: read circle.jpg and add a letter A in the center of the circle and save it as circleA.jpg
